1-Bromo-2-methylpropane(Cas 78-77-3) Usage
|
Safety Profile |
Questionable carcinogen with experimental neoplastigenic data. Moderately toxic by intraperitoneal route. A dangerous fire hazard when exposed to heat or flame. When heated to decomposition it emits toxic fumes of Br-. See also BROMIDES. |
|
Purification Methods |
Partially hydrolyse it to remove any tertiary alkyl halide, then fractionally distil it, then wash it with conc H2SO4, water and aqueous K2CO3, then redistil it from dry K2CO3. [Dunbar & Hammett J Am Chem Soc 72 109 1950, Beilstein 1 IV 294.] |
